hello list,
I have a problem when I try to use jit.gl.slab on a Mac with multiple
graphic cards where monitors are attached. The Computer I use is a Mac
Quad (4*2.5 GHz, 4.5 GB Ram) with three PCI express graphic cards. this
is one Nvidia gforce 7800Gt and two nvidia gforce 6600. as long as
monitors (2) are attached to only one graphic card jit.gl.slab works
just like expected. if I attach a monitor to a second graphic card
jit.gl.slab doesn’t operate any more and the following error messages
appear in the max window:

Please try the 1.6.3 beta posted previously on the list. This fix
among others is present. I’ve added the message below for your
convenience.

Beta versions of Jitter 1.6.3 for OS X Universal Binary and Windows
XP are now available for download at the following links. Release
notes at bottom, but this release will be especially useful for
anyone using spigot~, Macintosh users with multiple graphics cards,
and people with stereo 3D graphics cards. Unfortunately we were not
able to reproduce the reported NVidia 7950 GX2 (multi-core) issues
using multiple NVidia 7300 cards (which seem to work well, btw), so
for the time being, we can’t claim to fully support this card. There
may be driver updates which solve these problems, however, and we’d
be interested to hear of any changes in behavior from users with 7950
GX2 graphics cards.

As always please let us know of any problems you encounter and
include example patches, steps to reproduce, and system information
with your report. While these versions seem to be pretty stable, as
always with beta software, it is not recommended for installation/
performance work, and recommended that you back up your work before
installing and more often while working with the software.
